freeroll final table 2pair

[kingofmirrors]

~24 man freeroll, winnings are points towards a leaderboard or cash for first place. At final table (9 players) I'm close to the chip lead or possibly the chip leader, there were no official chip counts. I have about 35k and the average stack is about 25k. Blinds 500/1000 with 100 ante.

Loose-ish slightly intoxicated guy with about 30k raises to 3000 from middle position, I call from the button with ATo. No other calls. Flop comes Ad Qd Ts and he bets 6000. I don't feel like laying this down, but I feel like calling is too dangerous and doesn't get anywhere given the size of the bet, pot, and stacks, and raising is iffy too because he's already committed 1/3 of his stack so it's going to be hard to move him off if he has decent draws or has me beat (wagering a lot of money that he can win by outdrawing me or already having me beat). What's the play here? Thanks...
